✨ Features

• 43 tools — the most comprehensive n8n MCP available
• Data Tables — full CRUD, the only MCP with this support
• Automatic retry — exponential backoff on rate limits (429) and server errors (5xx)
• Configurable timeout — prevent hung requests (default 30s)
• Zero external dependencies — only MCP SDK + Zod
• TypeScript strict mode — fully typed, safe, and maintainable
• Node 16+ compatible — native fetch with http/https fallback

---

🔒 Security

• API keys are never hardcoded — loaded exclusively from environment variables
• Credential data is redacted in list responses (n8n API behavior)
• All IDs are sanitized with encodeURIComponent to prevent path traversal
• No sensitive data is logged or exposed in error messages
